Description

Technical Field

[0001] This utility model relates to the field of engine component technology, and more specifically, it relates to an engine cover that facilitates heat dissipation. Background Technology

[0002] While some progress has been made in the design of engine hoods for B-series engines to facilitate heat dissipation in existing automotive engineering technologies—B-series engines are a series of four-cylinder gasoline engines developed by Honda Motor Co., Ltd. and widely used in many models of Honda and Acura brands—there are still some obvious shortcomings and challenges in actual application, especially in improving heat dissipation efficiency and protecting the vehicle body.

[0003] First, regarding the high heat generated during engine operation, this has long been a problem that has plagued automotive engineers. During operation, the engine generates a large amount of heat, which not only affects the engine's performance and lifespan but also has an adverse effect on surrounding body parts, especially the hood. As a component that directly covers the engine and is in close proximity to the front hood, the hood is subjected to high temperatures for a long time. This causes the paint on the hood surface to age faster, leading to fading, cracking, and even peeling. This not only affects the vehicle's appearance but also reduces the body's corrosion resistance and shortens the vehicle's lifespan. More seriously, aging paint may expose metal parts, accelerating the corrosion of the hood and ultimately affecting the vehicle's structural integrity and safety.

[0004] Secondly, the heat dissipation methods commonly used in existing technologies have obvious limitations. The most common approach is to open heat dissipation holes or add fans on the engine hood. Although opening heat dissipation holes and adding fans can increase air circulation to a certain extent, this method can often only achieve local heat dissipation and cannot achieve uniform cooling. Moreover, if the heat dissipation holes are not designed properly, they may affect the structural strength of the engine hood and even become a safety hazard in extreme cases. More importantly, neither of these two methods can meet the heat dissipation requirements of the engine under different operating conditions and achieve efficient heat dissipation.

[0005] In addition, some advanced designs employ coolant circulation systems to achieve uniform cooling of the engine hood. Theoretically, this method can achieve better heat dissipation, but it still has some problems in practical applications. The main problem is that the input and output speeds of the coolant are usually fixed and cannot be flexibly adjusted according to the actual operating conditions of the engine and the ambient temperature. This means that the engine may be over-cooled and waste energy when operating at low loads, while it may not provide sufficient cooling when operating at high loads. At the same time, the fixed coolant circulation speed cannot cope with sudden temperature changes, such as the sharp rise in engine temperature during rapid acceleration or climbing. This lack of flexibility not only reduces the efficiency of the cooling system, but may also affect the overall performance and lifespan of the engine. Utility Model Content

[0016] The present invention is further provided with a detachable filter screen on one side of the mounting frame, the filter screen being provided to prevent foreign objects from entering the fan when the fan is not running.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides an engine cover that facilitates heat dissipation, and has the following beneficial effects:

[0019] 1. The innovative design of the cooling system cleverly solves the problem of low heat dissipation efficiency in traditional engine hoods. It consists of components such as cooling pipes, mounting frames, fans, and bolts. The cooling pipes are installed on one side of the hood and connected to the main cooling pipes, forming a closed-loop cooling system. The removable mounting frame design increases the convenience of maintenance, while the fan greatly improves heat dissipation efficiency. The heat-conducting fins on the outside of the cooling pipes further enhance heat transfer and accelerate the cooling speed of the coolant. The removable filter on one side of the mounting frame not only prevents debris from entering but also facilitates cleaning and maintenance. This design achieves high heat dissipation for the engine hood, effectively reducing the surface temperature of the engine hood and front hood, delaying paint aging, improving the vehicle's aesthetics and service life, and effectively preventing metal parts from being exposed and corroded, ensuring the structural integrity and safety of the vehicle.

[0020] 2. The water-cooling device cleverly solves the problems of localized heat dissipation and uneven effect of traditional heat dissipation methods. It includes components such as a main flow pipe, a branch pipe, a fixed plate, and a delivery pump. The branch pipe is installed above the hood and forms a cooling network covering the entire hood through its connection with the main flow pipe. The delivery pump ensures continuous circulation of coolant. This design achieves comprehensive and uniform cooling of the hood, overcoming the shortcomings of traditional heat dissipation holes or fan methods that can only dissipate heat locally. It not only improves heat dissipation efficiency, but also avoids the impact on the structural strength of the hood and eliminates potential safety hazards. In addition, this closed-loop water-cooling system can provide sufficient cooling effect under high load operation.

[0021] 3. The ingenious design of the control device solves the problem of the lack of flexibility in the coolant circulation system. It consists of components such as a motor, rigid pipe, driven wheel, service sleeve, connecting pipe, driving wheel, connecting plate, adapter pipe, adapter rod, adjusting sleeve, adjusting rod, through hole, and adapter plate. This complex mechanical structure enables precise adjustment of the coolant delivery speed. The motor drives the driving wheel through a reducer, which in turn drives the driven wheel and service sleeve to rotate. Finally, the linear movement of the adapter rod is achieved through the threaded connection between the adjusting sleeve and the adjusting rod, thereby changing the number of open through holes and adjusting the coolant flow rate. This design allows the cooling system to flexibly adjust the coolant delivery speed according to the actual operating conditions of the engine and the ambient temperature, effectively solving the problem of low efficiency of fixed-speed circulation systems under different operating conditions. It can avoid overcooling when the engine is running at low load, saving energy; and provide sufficient cooling effect in a timely manner when running at high load or experiencing sudden temperature changes, protecting engine performance and extending its service life.

[0031] Please see Figures 1-5 An engine hood for easy heat dissipation includes a hood 1, characterized in that: a water cooling device is provided on the outer side of the hood 1, the water cooling device including a main flow pipe 2, a branch pipe 3, a fixing plate 4, and a delivery pump 5, the branch pipe 3 covering the hood 1, two main flow pipes 2 respectively connected to both ends of the branch pipe 3, the delivery pump 5 connected to one of the main flow pipes 2, and a regulating device connected to one end of the main flow pipe 2, the regulating device including a motor 6, a rigid pipe 7, a driven wheel 8, a sleeve 9, a connecting pipe 10, a driving wheel 11, a connecting plate 12, an adapter pipe 13, an adapter rod 14, an adjusting sleeve 15, an adjusting rod 16, a through hole 17, and an adapter plate 1. 8. The motor 6 is located on one side of the connecting plate 12. The two ends of the sleeve 9 are rotatably connected to the rigid pipe 7 and the connecting pipe 10 respectively. The driven wheel 8 is fixedly connected to the outside of the sleeve 9. The driving wheel 11 meshes with the driven wheel 8. The connecting plate 12 is fixedly connected to the outside of the rigid pipe 7. The adapter pipe 13 is fixedly connected to the inner wall of the rigid pipe 7 through the adapter plate 18. The adapter rod 14 is slidably set in the adapter pipe 13. The adjusting sleeve 15 and the adjusting rod 16 are movably connected by threads. The adjusting rod 16 is fixedly connected to one end of the adapter rod 14. Multiple through holes 17 are opened on the side wall of the adapter pipe 13. A heat dissipation device is provided on one side of the cover 1.

[0032] A reducer 19 is detachably provided on one side of the connecting plate 12. The input end of the reducer 19 is connected to the output end of the motor 6, and the output end of the reducer 19 is connected to the drive wheel 11.

[0033] A slide rail 20 is fixedly provided on the inner side of the adapter tube 13, and a corresponding slide groove 21 is provided on the outer side of the adapter rod 14. The slide groove 21 is adapted to the slide rail 20.

[0034] A connecting rod 22 is fixedly installed inside the sleeve 9, and the other end of the connecting rod 22 is fixedly connected to the outside of the adjusting sleeve 15.

[0035] One end of the adjusting rod 16 is fixedly connected to a limiting plate 23.

[0036] In this embodiment, when the coolant delivery speed needs to be adjusted, the motor 6 is turned on. After being decelerated by the reducer 19, the motor 6 drives the drive wheel 11 to rotate. The drive wheel 11 then drives the driven wheel 8, which in turn drives the sleeve 9 to rotate. The sleeve 9 then drives the adjusting sleeve 15 to rotate via the connecting rod 22. Since the adjusting sleeve 15 is movably connected to the adjusting rod 16 via a thread, and the slide rail 20 and the slide groove 21 limit the adapter rod 14, the adapter rod 14 and the adjusting rod 16 will not rotate. The adjusting rod 16 will then drive the adapter rod 14 to slide along the slide rail 20 and the slide groove 21 in the adapter tube 13. This changes the number of through holes 17 on the side wall of the open adapter tube 13, thus changing the volume of coolant passing through and consequently changing the coolant delivery speed. Once the coolant delivery speed is adjusted appropriately, the motor 6 is turned off.

[0037] Please see Figures 1-4 As one embodiment of the heat dissipation device: the heat dissipation device includes a cooling pipe 24, a mounting frame 25, a fan 26 and bolts 27. The cooling pipe 24 is installed on one side of the cover 1, and both ends of the cooling pipe 24 are respectively connected to one end of two main pipes 2. The mounting frame 25 is detachably installed on one side of the cooling pipe 24 by bolts 27, and the fan 26 is detachably installed in the mounting frame 25.

[0038] A heat-conducting fin 28 is fixedly provided on the outside of the cooling pipe 24.

[0039] A filter screen 29 is detachably provided on one side of the mounting frame 25.

[0040] More specifically, when the temperature of the engine hood 1 gradually rises, the delivery pump 5 is turned on, and the delivery pump 5 draws out the coolant from the cooling pipe 24. Then, it is delivered to each branch pipe 3 through the main flow pipe 2 connected to the output end of the delivery pump 5. Then, heat exchange is carried out between the branch pipe 3 and the surface of the engine hood 1, thereby achieving efficient and uniform heat dissipation of the engine hood 1. After the heat exchange is completed, the coolant in the branch pipe 3 is delivered to the main flow pipe 2 connected to the other end of the branch pipe 3. Then, it is delivered back to the cooling pipe 24 through the main flow pipe 2. Then, the fan 26 installed in the mounting frame 25 is turned on. Then, the fan 26 draws the heat carried by the coolant in the cooling pipe 24 into the cooling pipe 24 and blows it out to the other side of the fan 26. The setting of the heat conduction plate 28 can improve the heat exchange efficiency of the cooling pipe 24, thereby accelerating the heat dissipation efficiency of the coolant in the cooling pipe 24, thus facilitating the recycling of the coolant.

[0041] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the coolant delivery speed, turn on motor 6. After being reduced in speed by reducer 19, motor 6 drives drive wheel 11 to rotate. Driven wheel 11 then drives driven wheel 8 to rotate. Driven wheel 8 then drives sleeve 9 to rotate. Sleeve 9 then drives adjusting sleeve 15 to rotate via connecting rod 22. Since adjusting sleeve 15 is movably connected to adjusting rod 16 via threads, and slide rail 20 and slide groove 21 limit the adapter rod 14, the adapter rod 14 and adjusting rod 16 will not rotate. Adjusting rod 16 will then drive adapter rod 14 to slide along slide rail 20 and slide groove 21 in adapter tube 13. The number of through holes 17 opened on the side wall of the open adapter tube 13 changes, thus changing the volume of coolant passing through, thereby changing the coolant delivery speed. Once the coolant delivery speed is adjusted appropriately, turn off motor 6.

[0042] As the temperature of the engine hood 1 gradually rises, the delivery pump 5 is turned on. The delivery pump 5 draws out the coolant from the cooling pipe 24 and then delivers it to each branch pipe 3 through the main flow pipe 2 connected to the output end of the delivery pump 5. Then, the coolant exchanges heat with the surface of the engine hood 1 through each branch pipe 3, thereby achieving efficient and uniform heat dissipation of the engine hood 1. After the heat exchange is completed, the coolant in the branch pipe 3 is delivered to the main flow pipe 2 connected to the other end of the branch pipe 3, and then is delivered back to the cooling pipe 24 through the main flow pipe 2. Then, the fan 26 installed in the mounting frame 25 is turned on. The fan 26 draws the heat carried by the coolant in the cooling pipe 24 into the cooling pipe 24 and then blows it out to the other side of the fan 26. The setting of the heat conduction plate 28 can improve the heat exchange efficiency of the cooling pipe 24, thereby accelerating the heat dissipation efficiency of the coolant in the cooling pipe 24, thus facilitating the recycling of the coolant.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
